Answer:
Carbon dioxide is added to the atmosphere naturally when organisms respire or decompose (decay), carbonate rocks are weathered, forest fires occur, and volcanoes erupt. Carbon dioxide is also added to the atmosphere through human activities, such as the burning of fossil fuels and forests and the production of cement.
Step-by-step explanation:
Answer:
B, D, C, A
Step-by-step explanation:
The question is asking to put the photographers into least to greast.
For the best case, I suggest you change them into decimals and put them in order.
Photgrapher A: 2/5 = 0.4 = 40%
Photographer B: 4% = 0.04 = 4%
Photographer C: 0.29 = 29%
Photographer D: 27/100 = 0.27 = 27%
Now put them into least to greatest.
Photographer B, Photographer D, Photographer C, And Photographer A
One solution was found : t ≤ -13 (number 4)
Pull out like factors :
-3t - 39 = -3 • (t + 13)
Divide both sides by -3
Remember to flip the inequality sign:
Solve Basic Inequality :
Subtract 13 from both sides to get t≤−13
The answer is 280 because if you multiply 400 by .3 you get 120 and if you subtract 120 from 400 you get 280
